Hi all-- LOVE ya BYC! Dh isn't so into it, but I'm gonna switch him. I'm planning on building a chicken tractor, probably an A-frame one that is super easy to build. Something for three to four girls. I will need something that is moveable, because our local ordinances say the coop has to be 25 feet from the property line. So I figure something moveable is best. One of my many questions is this--for a tractor like that, what is required in the way of pest-proofing the bottom against diggers? Should I add some kind of mesh skirt 6 inches in each direction? Or do you actually put mesh on the floor too? Still researching...but I miss having chickens. I grew up on a farm and we had tons. Thanks!
